AIR-VALVE FOR CARBURETERS.

Be it known that 1, JOHN C. Mn'raenn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use-- ful Improvements 1n Air-Valves for Carbureters, of which the following, taken in connection with the drawing, is a description. My invention has for its object the production of a'carbureter valve of a design known as the sleeve type.

nection with a carburetei, and which is connected by means of a flexible shaft to mech-' anism for operating the same which is secured to the steering rod, in the event the device is used on an automobile, or at any other convenient place if used on "difierent kinds of machines. v t

A further object of my invention is to provide a regulator. which will not only accomplish the advantages above set forth, but at the same time effect a very material saving in the amount of gasolene required for the operation of the machine;

In the accompanying drawings I have illustrated what I- now consider the preferred form of my invention, although it is obvious that other methods for carrying out the operation thereof may be employed without departing from the spirit of my invention and in these drawings Figure 1 is a side elevation of'a carbureter with my valve secured thereto, together with the operating .mechanism secured to the steering rod of an automobile, the flexible shaft being broken; Fig. 2 is a longitudinal sectional view of the valve; Fig. 3 is a transverse sectional view taken on line 33 of Fig. 2; Fig. 4 is a plan view of the operating attachment secured to the steering rod of an automobile.

. Referring to the drawing A represents the carbureting chamber of the carbureter,

- which may be of any well known type, and

which will therefore not. be. further explained. Entering the carbureting chamber preferably at the bottom thereof is a coupling B to which is secured the barrel B of Specification of Letters Patent.

the valve which is cylindrical in form and which is provided with apertures b extending helically around the same. A hexagon nut b is formed integrally with the barrel, by means of which it may be readily turned into position. .Slidin in this barrel is a sleeve C which is provlded with a transverse partition 0, through which partition extends the wire C, which is secured in'fixed position by means of the set screw 0. One end of the barrel B is closed by means of the plug D into which is secured the flexible tubular casing D which is fixed in position by the screw D l The wire 0' extends through the flexible tubular casing D and connected with the operating lever E, which is secured to the bracket E at e. The bracket E is rigidly secured in this instance: to the steering rod F of an automobile. This bracket E is provided with an arm 6 which is curved on.

the arc of a circle, as shown in Fig. 1. One Y side of this arm is provided with a knurled or otherwise roughened surface to afford friction as the lever is moved across the same.

In operation the gasolene or other material being used, is fed through the pipe G to the carbureting chamber A from whence the. mixture makes its exit to the engine through. the openin G. The operation of the valve is eifecte by the attendant moving the lever E across the roughened surface eflwhich action through the wire C", extending through the flexible tubular casing, moves the sleeve C in the barrel to open or close some of the holes 6 thereby increasing or decreasing the amount of air passing therethrough to the carbureting chamber A- The sleeve C is made to fit closely in the barrel B and by the helically arranged open-. ings b the amount of air allowed to pass therethrough may be regulated to a nicety. By carburizing in the chamber as heretofore explained with my improved valve I am able to run an automobile four to five miles farther with each gallon of gasolene used than can be done without the use of this valve.
